Camera problems

Support and Help
1

I have a Clevo NL55P laptop running Ubuntu 24.04.2 LTS and Firefox 136.0.1 I keep my laptop updated at all times, the last time Firefox was updated was about 4 days ago.

My webcam is a Bisoncam NB Pro.

I am having trouble with my Facebook account being suspended with no explanation and when trying to follow their instructions for validating my ID, I could not use my call phone (in a dead spot that extends for several miles in every direction), so went to the next step which was to submit a live video on my face.

When I could not accomplish this, I went into settings in Firefox and discovered that I could not add any websites to allow access to the webcam. I have never used the webcam on this laptop because I have never had to use it. The webcam works with Camera and Cheese.

I did get a suggestion to install Firefox from Mozilla:
“ Try downloading Firefox from Mozilla, run firefox-bin from the folder and see if you have the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release”"

Will this work or will it break something?

Why should I have to do this when I keep my laptop updated at all times?

That camera should just work OOTB, it is fully supported by the uvcvideo driver…

Does your laptop have a hardware key to toggle it on/off on a hardware level ? AFAIK on Clevo systems this is usually F10

To check if your camera is detected and on try:

dmesg | grep -i uvcvideo

It should show something about the camera…

Regarding Firefox I highly doubt moving to the Mozilla deb makes any difference, the snap has the exact same access to /dev/video* as the deb unless you explicitly disconnected the camera snap interface of the package with snap disconnect... or via the permission settings GUI

Tried ```
dmesg | grep -i uvcvideo

here is what I got;

dmesg: read kernel buffer failed: Operation not permitted

I just found out that the camera is off by default and won’t start until I run Camera first, not even Cheese.

I will try installing the deb file

Ah, sorry with recent kernels you will need sudo with dmesg, I always forget that…

So you want:

sudo dmesg | grep -i uvcvideo

If you really find a difference with the deb (which again, is highly unlikely for a uvc camera) please open a bug for the snap so this can be researched since it would technically not be possible for that type of camera to actually make any difference…

I did install the deb (after several tries). Because of the browser install I had to re-confirm my id with yahoo (I was able to get a text with the code (not usually possible) to sign in. I then went to Facebook and finally got to do the video selfie but now have to wait for 24 to 48 hours for Facebook AI to determine if I can stay on Facebook. They still haven’t told me what I did wrong.

Thanks for the help and wish me luck with Facebook.
